Definitions

  • the latest OCT technology employs a single-mode optical fiber with distal side-viewing optics introduced into the accessory channel of a conventional white-light endoscope.
  • the viewing direction of the OCT fiber is either linearly scanned to and fro over an approximate 2 mm distance, or is rotated via a flexible guide-wire or interlocking gear mechanism at several revolutions per second.
  • the reference arm length outside the endoscope is rapidly varied via an optical phase delay to generate depth scans (i.e. A-scans).
  • these OCT systems operate at frame rates up to conventional video rates but more typically at 4 to 8 frames per second, with a frame presenting a fully circumferential view to a depth of 2 to 3 mm.
  • Figure 13a is a schematic of an experimental setup used to investigate cross-talk between optical channels sharing components
  • the overall general layout of the basic optical elements of the apparatus of the present invention comprises a plurality of optical sources 50, a plurality of tree couplers 52, a plurality of 3 dB couplers 54, a fiber bundle tip 56, a plurality of detectors 58, a plurality of demodulators 60 and an optical delay generator 64.
  • the plurality of optical sources 50 which may be lasers, are connected to the plurality of tree couplers 52. More than one laser may be needed to ensure that adequate optical radiation is provided to each of the fibers (i.e. channels) in the tip 56.
  • Each tree coupler 52 couples a respective optical source 50 to a subset of the plurality of 3 dB couplers 54.
  • the coherence length will be approximately 4.5 to 6 ⁇ m. Since the spatial sampling interval in the axial direction is about 2 ⁇ m, which is smaller than half of the coherence length, the image is reasonably sampled in the axial direction. Using a near diffraction-limited focusing lens as the focusing lens 14, the beam spot size should be about 5 ⁇ m. Since the spatial sampling interval in the lateral direction varies from 3.86 to 5.59 ⁇ m, the image is slightly under sampled, given that the beam waist size is about 5 ⁇ m.
  • such reflections may contribute to image noise if the light from these pathways produced interference fringes having a significant intensity.
  • this kind of noise may be secondary to the channel cross talk previously described because of its lower intensity.
  • Analysis of the system revealed that the worst-case scenario for interference of such back-reflections involves one reflection from a connector. For example, light from the following optical path:
  • Optical path lengths BSi -> ODGE and BS 2 - ODGE are essentially predetermined by the lengths of the fiber pigtails coming from beam splitters BSi and BS 2 .
  • Optical path lengths BSi - Si and BS 2 -> S 2 are deliberately matched to the predetermined corresponding reference arm lengths.
  • Typically manufactured fiber lengths differed by several tens of millimeters which is at least one order of magnitude greater than the scanning depth of the optical delay generator ODG E . Therefore, this type of cross talk should not be a problem in a dual channel system.

Abstract

Cette invention a trait à une technique et à l'appareil correspondant permettant d'examiner la microstructure sub superficielle d'un échantillon. Un rayonnement émanant de plusieurs sources de rayonnement se déplace le long d'un premier trajet optique. Dans ce premier trajet optique, un dispositif focalise le rayonnement optique émanant de chaque source dans plusieurs points focaux le long dudit trajet afin d'assurer une couverture quasiment continue d'une partie sélectionnée de celui-ci. De la sorte, un échantillon se trouvant à l'intérieur de la partie sélectionnée du premier trajet optique est scanné dans toute cette partie sélectionnée.
